;32-bit/64-bit Architecture | |||
: This refers to the architecture of the CPU, datapath widths, integer size, and memory addresses. 32-bit and 64-bit hardware are not interchangeable. 32-bit must be used with 32-bit. In most things, 64-bit is backwards compatible with 32-bit; however, you will benefit most by keeping 64-bit with 64-bit; not mixing the two. | |||
;Core | |||
: A core is the actual central processing unit. It receives and executes instructions. | |||
;DMI | |||
: The Direct Media Interface (DMI) is the connection between the northbidge and the southbridge on the motherboard. It is measured in gigabits per second (Gb/s) or gigatransfers per second (GT/s). This is for Intel CPUs only. | |||
;Frequency | |||
: Frequency (sometimes referred to as Operating Frequency) is the speed at which the CPU operates. This is measured in gigahertz (GHz). The higher the GHZ the faster the CPU operates. | |||
;Hyper-threading | |||
: Hyper-threading uses processor resources more efficiently, enabling multiple threads to run on each core. As a performance feature, hyper-threading also increases processor throughput, improving overall performance on threaded software. (Intel only) | |||
;Mulit-core | |||
: A CPU which houses multiple cores is referred to as multi-core. A multi-core CPU can run multiple instructions at the same time, increasing overall speed. Multi-core CPUs come in 2-core, 3-core, 4-core, 6-core, and 8-core varieties. | |||
;L1, L2, L3 Cache | |||
: CPU utilize multi-level caches to reduce the average time to access memory. These caches are a smaller, but faster memory similar to RAM which stores copies of the data from the most frequently used system RAM locations. | |||
;Socket | |||
: The CPU socket type is the type of connection the CPU uses to connect to the motherboard. The CPU and motherboard socket types must match in order to use a specific CPU with a specific motherboard. | |||
